Score to Grade Conversion This program converts numerical scores to letter grades using a switch-case structure. #include <stdio.h> char calculate_grade(int value); int main() { int input; char result; while (scanf("%d", &input) != EOF) { result = calculate_grade(input); printf(&...

Number Theory Fundamentals Extended Euclidean Algorithm and Linear Diophantine Equations For integers a and b, the equation ax + by = d has integer solutions if and only if the greatest common divisor gcd(a, b) divides d. This is known as Bézout's Identity. The extended Euclidean algorithm alows us...
